Raster art vs. Vector art

Raster artwork is any digital art composed of horizontal and vertical rows of pixels. As a result, when raster images are enlarged, the image quality diminishes significantly. Typical raster file types include .psd, .tif, .jpg, .gif, and .bmp.

Vector artwork is digital art composed of mathematical lines and curves. As a result, vector images can be reduced or enlarged in size indefinitely, without any loss in image quality. Typical vector file types include .ai, .eps, .ps, .indd, .pdf, and .cdr.

If you upload a raster image in CustomInk's Design Lab, and you would like it to appear exactly as-is on your shirts (i.e. a photograph), the minimum DPI (dots per inch) requirement is 200 at print size. If your image is NOT 200 DPI at the size you want it to be printed, or if you submit a raster clipart-like image, one of our expert production artists will recreate your image as vector art, free of charge! So you can be confident that no matter what, we'll do everything possible to get your image on your shirts, exactly the way you want it.
